Pre-employment Polygraph Examination
Specific/Diagnostic Polygraph Examination
Periodic/Routine Polygraph Examination

A pre-employment polygraph examination is a test conducted on all new applicants or prospective employees as a means of gathering information, verifying information submitted by the applicants during their application process and interview.
The pre-employment polygraph examination is designed to uncover information that standard employment screening methods may not identify. This includes any omissions of pertinent details concerning prior employment, undisclosed criminal activity, substance abuse, affiliations with organized groups, and prior terminations, among other factors.
Polygraph examinations can reveal undisclosed information such as involvement in criminal activities, substance abuse, and other behaviours that might not be captured in background checks.
Polygraph examinations can evaluate honesty and integrity by analysing physiological responses to targeted questions.

Polygraph examinations are often employed as an auxiliary method in investigative processes. In the context of a criminal incident or similar issues within the workplace, these examinations can be an effective forensic tool. As a resource in investigations, polygraph examinations can provide insights that may not be available through other means. Many organisations find polygraphs particularly useful for narrowing down the pool of suspects.
The results often help identify individuals related to the matter under investigation, and, in certain cases, admissions of guilt may occur during or after the examination. Additionally, relevant information may be acquired during the pre-examination interview, which can be corroborated with previous statements or other pertinent facts of the case. Although a polygraph examination does not substitute for a thorough investigation, it can significantly enhance the investigative process.
The outcomes of such examinations can also be included in the evidence package to bolster cases in disciplinary enquiries. Specific polygraph testing is an important investigative resource that can expedite both corporate and criminal investigations toward successful resolutions. These examinations typically focus on a single issue, as suggested by the term "diagnostic," but can also be broadened to encompass specific events, dates, times, and other details pertinent to a particular matter under investigation.

Periodic or routine polygraph examinations are conducted on a regular schedule as a proactive strategy to monitor potential criminal or unethical conduct within the organisation. The awareness that employees will participate in these routine tests serves as a deterrent, thereby decreasing the likelihood of unethical or illegal behaviour.
These examinations have been effectively utilized across various sectors of numerous industries. In instances where inappropriate behaviour is detected, it is likely to be revealed during the screening process, prompting further investigation by the organisation. Additionally, these tests promote a culture of integrity and act as an extra deterrent against possible misconduct in the workplace.
Periodic polygraph testing is a valuable tool for verifying the integrity of current employees. It enhances trust in individuals who have access to sensitive systems and information, while also addressing any potential affiliations with criminal entities or competing organizations.
This periodic polygraph testing adopts a screening format that covers a wider array of topics over an extended timeframe, rather than concentrating on a single incident. The primary goal is to collect information regarding an employee’s historical behaviour or character, which may include potential illicit drug use, involvement in criminal activities, or breaches of company policies during previous employment.
